Are you bleeding in the right order? Sounds like your master cylinder might be going, especially if its the original one. Mine went on my 02 which im assuming had an internal leak that was drawing air in. Turned my brake fluid slightly green from all the moisture. I had no leaks and bleeding my backs were odd until I replaced the cylinder.

Check flex lines for blockage. Ford lines like to crumble internally and block fluid. Will also cause “stuck” caliper by refusing to let fluid return. Just a thought.
